Notes

1. VIL = VSS; VIH = VDD; open drain outputs connected to VSS; all other outputs, including XTAL2, open (typical values

at 25 °C with crystal connected between XTAL1 and XTAL2).

2. VIL = VSS; VIH = VDD; RESET and T1 at VSS; INT/T0 at VDD; crystal connected between XTAL1 and XTAL2; open

drain outputs connected to VSS; all other outputs open.
